This study comparatively analyzed the impact of childcare workforce cost on fertility rates across different countries. In the cases of Nordic countries, comprehensive childcare support policies and subsidies for childcare workforce costs were found to have a positive impact on fertility rates. In contrast, high childcare burden and economic pressures were identified as major factors contributing to declining fertility rates in East Asian countries. In developing countries, the effectiveness of childcare support policies varied depending on the socioeconomic context. This study suggests that the impact of childcare workforce cost on fertility rates manifests in diverse patterns across countries, and effective childcare support policies require tailored approaches that consider each country's specific circumstances. In the future, increased social investment in childcare and the spread of a culture that respects the value of care are necessary.

농업부문이 사회에 제공하는 다양한 긍정적 외부효과가 인정됨에 따라, 대부분의 농업생산기반시설은 국부를 증진시키는 사회간접자본으로 인식되고 있다. 과거에는 수리시설을 비롯한 기반시설이 단지 생산성 향상을 위한 사회적 투자로 간주되었으며 따라서 사업에 대한 경제성 분석 또한 직접적인 경제적 효과에 대한 편익비용분석에 국한되었다. 그러나 최근에는 농업 및 생산기반시설이 제공하는 비시장적 가치가 점차 인정됨에 따라 그러한 가치 또한 경제성분석에 포함될 수 있다

Odor problem of livestock operation is important issue in a local community. I quantified the property price impact of 199 livestock operations for 3,355 housing sales in the U.S (Colorado). Spatial hedonic model was adopted to deal with spatial autocorrelation in housing market. Small beef and dairy operations, which are the traditional agricultural sector, seem to create a positive rural lifestyle amenity effect. However, the impact of livestock operation on rural residential sales turns to negative if the operation is over a certain size and species. Large hog and sheep operation seems to bring fatal economic loss from the local community perspective if it close to residential area. Livestock odor is one of the negative externality, the results provide the potential social cost of the livestock sector in the region. Policy makers may incorporate this social cost in the regional planning to minimize the social and maximize the development effect. Therefore, local officials and private individuals should carefully consider the location and characteristics of new residential properties and livestock operations alike.

전력산업 구조개편이후 송전체제, 특히 송전요금체계에 관한 연구가 미흡한 가운데 자연적 독점을 유지하게 될 송전에 대한 정부의 규제가 중요성을 가지게 되었다. 본 연구에서는 여러 정부 규제방안들을 비교 검토하여 최적방안 모색을 위한 방향을 제시하고자 한다. 송전요금은 비용반영 투명성, 비(非)차별, 경쟁 등의 원칙을 지켜야 하고 이런 송전요금에는 경제적 효율성 사회 복지, 비용 최소 운영 등의 증진을 위해 한계비용이 반영되어야 한다. 하지만, 송전 네트웍은 규모의 경제에 종속되는 장기 투자로 구성된다. 이런 조건에서는 한계비용은 정의되기 어렵다. 그러므로 송전요금은 단기적 한계비용들의 신호와 장기적으로는 적절한 비용회수의 보장들과의 타협조정을 해야 한다. 네트웍 요금은 경쟁 정책의 원칙을 준수할 필요가 있으며 어떤 한 네트웍 회사도 과도한 요금을 부과한다든지 또는 사용자들을 차별한다든지 또는 약탈적(predatory) 방식으로 행동할 시에는 지배적 지위 남용에 대해 벌칙을 당하게 되어있다. 송전요금에 관한 결정은 공공서비스 의무비용, 특정 소비자그룹 우대를 위한 국가 정책들과 같은 사회적 목적들에 의해 제한을 받는다. 현존하는 대표적인 정부규제방안인 가격상한제와 투자보수율 규제방식을 검토한 결과 유도된 중요한 사실은 가격상한제 규제방식이 기업들로 하여금 위험(risk)에 좀 더 종속되게 만들지만 반면에 비용절감을 위한 강력한 인센티브를 주어 효율성 향상을 기할 수 있게 만든다는 것이다. 이러한 사실은 가격상한제 규제방식이 정부규제의 기본원칙에 더 많이 부합되며 궁극적인 경제체제의 목표인 자원의 효율적 배분에 더 가깝다는 것을 의미한다.

The aim of this paper is to research the changes of social welfare by internalizing external cost, especially the maintenance cost. Main target of this paper is the Cheonan$\sim$Nonsan Line, where private capital highway, national highway and local road are competing against each other. Considering the realistic difficulties in applying the First Best pricing, this paper applied the Second Best pricing, applying the maintenance cost, in lieu of the already mentioned. The demand functions of the toll roads were built through regression analysis. By reflecting the maintenance cost to the toll fee, It was able to confirm the variation of social welfare deriving from the traffic assign change but also the aspects of toll revenue at the same time. Result of applying the Second Best pricing shows merely a small change in social welfare. However, in the aspect of finance, it is analyzed that there will be about 13 billion won worth of financial effectiveness which will contribute to the reduction of the national financial support.

Recently it has been encouraged in developed countries that labor force participation of the elderly is one of the means to cut down the cost of social welfare for them. However, empirical studies have rarely explored how work in later life contributes to national economy. Especially, even though 56.6 percent of elderly workers aged 65 and older engaged in agriculture and forestry in Korea, their contribution has been socio-economically overlooked. This study aims at examining the effect of farming labor in later life on social welfare expenditure. For this purpose, social welfare expenditure was defined as social benefits provided for the elderly by the social security in public sector and measured as transportation allowance, pension, livelihood aid, medical aid, and health insurance in 2003. Data were obtained from National Health Insurance Cooperation and 37 town/village offices and analyzed by 3 age groups; 65~74, 75~84, and 85 and over using SPSS/PC windows program. Results showed that both livelihood and medical support in all age groups were expended more to non-farm than to farm workers. The amount differences per person between them were 113,959~361,132 won in livelihood support and 15,644~51,418 won in medical support. Also, participation in farming influence reduction of livelihood expenditure for the group 65~74 and 75~84 and that of medical expenditure only for the group 65~74. Based on these results, it was estimated the amount of social welfare expenditure reduced by farming labor in later life. The limit of this study and the policy implications of the results are discussed.

인간에 대한 신고전파 경제학의 가정을 확장할 경우, 인간은 사회적 선호를 가지고 있고 규범을 사용하며 전통과 관습으로부터 자유롭지 못한 존재라고 볼 수 있다. 이 논문에서는 특히 사회적 규범을 따르는 개인의 행위를 명시적으로 고려하여 내면화된 사회적 규범을 따르는 경우에 얻는 심리적 만족감과 따르지 않을 경우 치러야 하는 심리적 비용을 δ 요인이라고 개념화하였다. 그리고 나서 이러한 δ 요인이 집단행동의 딜레마상황을 해결하는데 어떤 순기능을 발휘하는지, 낮은 행정비용으로 정책의 효과성을 제고하는데 어떻게 기여하는지를 살펴보았다. 또한 이러한 #x03B4; 요인이 정책관련 변수와 상호작용하여 어떻게 정책의 목표를 달성하는데 방해가 될 수 있는지도 들여다 보았다. 이를 위해 다양한 (가상적) 정책사례들을 살펴본 후 정책이 δ 요인과 상호보완적으로 작용하여 정책집행의 성공에 도움이 되는 공통된 조건이 무엇인지를 도출하였다. 사회적 규범을 따르는 개인들의 비율이 클수록, 정책대상이 되는 개인들의 행위에 대한 관측가능성의 정도가 높을수록, 사회규범의 준수가 개인의 이익과 연계될수록, 정책으로 실현하고자 하는 가치와 기존 규범과의 충돌이 최소화될수록, 합리적 이기주의자에 대한 통제가 충분히 이루어질수록 δ 요인은 정책과 보완적 관계가 형성되어 정책집행의 성공가능성을 높이는 것으로 분석되었다.

This paper proposed a general formulation of Life-Cycle Cost (LCC) models and LCC effective design system models of steel bridges suitable for practical implementation. An LCC model for the optimum design of steel bridges included initial cost and direct/indirect rehabilitation costs of a steel bridge as well as repair/replacement costs, loss of contents or fatality and injury losses, road user costs, and indirect socioeconomic losses. The new road user cost model and regional socioeconomic losses model were especially considered because of the traffic network. Illustrative design examples of an actual steel box girder and an orthotropic steel deck bridge were discussed to demonstrate the LCC effectiveness of the design of steel bridges. Based on the results of the numerical investigation, the LCC-effective optimum design of steel bridges based on the proposed LCC model was found to lead to a more rational, economical, and safer design compared with the initial cost-optimum design and the conventional code-based design.

In this study, DEA (Data Envelopment Analysis) was carried out on the four bridges, which have the same extension (L=1,615m), in order to select the most superior, economical method of construction using the LCC concept of each bridge structure in the case of the Ulsan-Pohang double track railway which is scheduled to be constructed. DEA models were analyzed with the CCR model, which was designed for the evaluation of relative efficiency of each model. The initial construction costs, maintenance costs, indirect costs (user costs + indirect loss of social costs), and life cycle costs were used as input variables, and average duration was applied as the output variable. LCC was applied to calculate the input variables, and to get the costs of LCC, 100 years of period and 4.83% of real discount rate were applied, and the costs are classified into initial construction, maintenance, user, and indirect loss of social cost. The analysis results showed that the Method 2 and 3 were evaluated as the most efficient, and the other alternatives were evaluated as the following order; Method 1, the default, and Method 4.
